ID2= (20-VD1-VD2)/5600 - VD2/3300.
=19V/5.6kOhm - 0.3V/3.3kOhm.
=3.393mA - 0.091.
So, 3.302mA.
=19V/5.6kOhm - 0.3V/3.3kOhm.
=3.393mA - 0.091.
So, 3.302mA.

ID2= (20-0.7-0.3)/5600 - 0.3/3300
=19/5600 - 0.3/3300
=0.003392857 - 0.0000909090
= 0.003301948 A .
i.e. 3.302 mA. The answer above has not taken into consideration the current flowing through the resistance 3K3 due to 0.3 V forward bias V of the diode.

As diode resistance is very small which allows maximum current to pass through it.
So (20-0.7-0.7)/5.6=3.3214mA.
So (20-0.7-0.7)/5.6=3.3214mA.

Formula .
ID2 = (E-Si-Ge)/R.
where :
R = 5.6K.
ID2 = (E-Si-Ge)/R.
where :
R = 5.6K.

@Sreekala K S,
How did you choose the resistance value in 5.6?

ID1 is Same as ID2 because they are connected in series.

It is the minimum amount of voltage which is required to operate components like for silicon diode it is 0.7 V while for Germanium Diode its 0.3 V.
